魔方又叫魔术方块，也称鲁比克方块。魔方是匈牙利布达佩斯建筑学院厄尔诺·鲁比克教授在1974年发明的。当初他发明魔方，仅仅是作为一种帮助学生增强空间思维能力的教学工具。而如今魔方作为一种智力玩具，已经风靡全球，并在国际范围内出现了多项以魔方为道具的竞技比赛。魔方包括三阶魔方和二阶魔方，其中，三阶魔方在日常生活中较为常见；二阶魔方与三阶魔方不同，二阶魔方只有八个角块在外层，其中一个角块固定，另外七个可以绕魔方的中心运动。
现有的公告号为CN210186414U的中国发明专利公开了一种具有定位系统的二阶魔方，包括一体成型的三维十字轴、设置在三维十字轴上的内芯组件、八个安装在内芯组件上的角块；所述内芯组件的外形轮廓呈圆形；八个角块两两拼接成正方体；所述内芯组件包括中心块、棱块、用于与角块连接的连接块和用于与角块连接的定位组件，所述中心块、定位组件设于三维十字轴上，所述棱块分别与中心块、连接块卡接，所述定位组件用于随与该定位组件连接的角块同步转动，所述定位组件分别与连接块、棱块卡接；所述定位组件包括中心定位块、棱边定位块和用于与角块连接的连接定位块，所述中心块、中心定位块分别通过弹性组件安装于三维十字轴上，所述中心块、中 心定位块可沿三维十字轴的延伸方向移动，所述中心定位块和棱块卡接，所述棱边定位块和连接块卡接，所述连接定位块用于随与该连接定位块连接的角块同步转动，所述棱边定位块分别与中心定位块、连接定位块卡接；所述中心定位块上设有定位板，所述棱边定位块上设有定位卡槽，所述定位板与定位卡槽卡接。
上述中的现有技术方案存在以下缺陷：上述的三维十字轴包括轴心和六根连杆，其结构简单；这种三维十字轴通过中心定位块和棱块实现定位，三个中心定位块和三个中心块与三维十字轴连接，由于中心定位块不能相对于三维十字轴转动，中心定位块可沿着三维十字轴长度方向来回往复运动；中心块不仅能相对于三维十字轴转动，而且能沿着三维十字轴长度方向来回往复运动，导致中心块与中心定位块不同，增加了生产中心块或中心定位块的成本；组装魔方时，必须严格区分中心块和中心定位块，否则魔方将不能正常转动，从而降低了组装魔方的效率；上述三维十字轴的二阶魔方的定位方式叫L型定位或者EG定位，三维十字轴主要作用是与中心块和中心定位块连接，其不直接参加魔方的定位。
发明内容
本发明的目的是提供一种用于魔方的中心轴，其提供了一种新的用于魔方的定位方式，中心轴与中心块组装时，无需区分，有利于提高组装魔方的效率。
本发明的上述发明目的是通过以下技术方案得以实现的：

具体实施方式
以下结合附图对本发明作进一步详细说明。
参照图1至图9，为本专利公开的魔方，魔方包括中心轴1、六个中心块本体2、十二个棱块3和八个角块本体4，中心轴1为三维轴，中心轴1的末端与中心块本体2连接，棱块3可滑动卡接在相邻两个中心块本体2之间，角块本体4可滑动卡接在相邻三个棱块3之间；其中，三个相邻的棱块3与中心轴1固定，不仅限制卡接在这三个相邻棱块3之间的角块本体4滑移，而且限制与这三个相邻棱块3卡接的中心块本体2的转动。
中心轴1包括六根连接轴11，六根连接轴11的一端端部相互固定；其中，两根连接轴11的轴线在同一直线上，且这两根连接轴11对称设置，相邻两根连接轴11垂直设置；其中，四根连接轴11的轴线位于同一平面内。中心轴1设有三块定位板12，三块定位板12相互垂直，三块定位板12形成三维平面；定位板12与垂直的两根连接 轴11的轴线位于同一平面内，三块定位板12的法线相交；定位板12位于垂直的两根连接轴11之间，定位板12的相邻两侧侧面分别与连接轴11固定，使得其中三根连接轴11的侧面分别与两块定位板12固定，且这三根连接轴11相互垂直；定位板12还可以位于垂直的两根连接轴11之间，定位板12的相邻两侧的一侧面与连接轴11固定，另一侧面与另一连接轴11之间存在间隙。中心轴1的末端设有连接槽13，连接槽13位于连接轴11远离其他连接轴11的一端，且连接槽13位于连接轴11的圆周，以便于利用连接槽13与中心块本体2连接固定。中心轴1一体成型，以减少制备中心轴1的加工步骤；中心轴1可用金属制备，如中心轴使用粉末冶金制备，中心轴1还可以使用塑胶制备，中心轴1还可以使用其它的材料制备。
中心块本体2包括中心块壳体21和设置在中心块壳体21内的卡环22，卡环22与中心轴1开设的连接槽13配合设置，即卡环22与连接轴11开设的连接槽13配合设置，中心块壳体21开设有连接孔211，连接轴11可活动穿过连接孔211伸入中心块壳体21内，中心块壳体21不仅可以沿着连接轴11长度方向来回往复运动，而且中心块壳体21可沿着连接轴11转动；卡环22与连接轴11的连接槽13卡接，实现中心块壳体21与连接轴11连接固定，即实现中心块本体2与中心轴1连接固定；中心块壳体21和卡环22之间设有复位机构23，复位机构23包括限位筒232和置于限位筒232内的复位弹簧231，限位筒232的开口朝向中心块壳体21的底部，复位弹簧231的一端与中心块壳体21抵触，另一端与限位筒232的筒底抵触，使得复位 弹簧231处于压缩状态；限位筒232的筒底开设有通孔233，连接轴11依次穿过连接孔211、复位弹簧231和通孔233的突出端通过连接槽13与卡环22卡接；限位筒232背离中心块壳体21的表面开设有凹槽234，凹槽234与通孔233连通，卡环22置于凹槽234内，且卡环22与凹槽234的槽底接触，以减少连接轴11和卡环22露出限位筒232的表面，使得中心块壳体21内更加紧凑，从而中心块本体2更加紧凑；凹槽234呈圆形设置，凹槽234的直径大于卡环22的宽度，以便于将卡环22从连接轴11的连接槽13拆下。
